No Sub Contracting

While we work with many great local trades, we never outsource the installation of our windows doors and conservatories. One of the reasons for that is that we want to make sure that you’re speaking to the same people every time. Open and honest lines of communication are important in any installation. And we want to make sure that you can come to us with any questions about our work.

The other reason we do the work ourselves is that we have enough experience in the industry to know the process intimately, whether you’re looking for an orangery or conservatory roof.

First Rate Materials

At Fortress, we use two of the best materials on the market: uPVC and aluminium. Both are incredibly weather resistant, and unlike timber, won’t warp or stain. Instead, they are long lasting with very little maintenance. Both require a simple wipe down with a damp cloth and soap.

Our quality fitting service will be able to offer you a variety of materials. You can look through our windows and doors to find which option works best for your Cheshire home. We offer the full range of uPVC windows and aluminium windows in a variety of styles for any home.
